Incorporating electronic information into Machine Learning potential energy surfaces via approaching the ground-state electronic energy as a function of atom-based electronic populations

Posted by klaurent Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Xiaowei Xie, Kristin A. Persson, David W. Small, , | Summary: Machine Learning (ML) approximations to Density Functional Theory (DFT) potential energy surfaces (PESs) are showing great promise for reducing the computational cost of accurate molecular simulations, but at present they are not applicable to varying […]

Kavli Affiliate: David A. Principe | First 5 Authors: Anastasiia V Uvarova, Hans Moritz Günther, David A. Principe, P. Christian Schneider, | Summary: Young stars accrete mass and angular momentum from their circumstellar disks. Some of them also drive outflows, which can be distinguished in optical forbidden emission lines (FELs). We analyze a sample of […]

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Jeroen Homan, Joe Bright, Sara E. Motta, Diego Altamirano, Zaven Arzoumanian | Summary: We present Neutron Star Interior Composition Explorer X-ray and Arcminute Microkelvin Imager Large Array radio observations of a rapid hard-to-soft state transition in the black hole X-ray transient MAXI J1820+070. During the transition […]
